Macroalgea (Eg. seaweed / nori)
Small crustaceans (Krill, mysis, artemia...)
Larger crustaceans (Shrimp, crabs...)
This spicies might be a threat to smaller fishes.
This species must be fed with an appropriately varied diet.
This species requires frequent feeding, at least a couple of times per day.
This species eats a great deal and demands an aquarium that can tolerate such a heavy load.
This species is very sensitive during transportation and acclimatizing into the aquarium.
This species will better acclimatize to the aquarium`s condition if introduced, when young.
Very small individuals can be very delicate.
This species revels in swimming and requires an aquarium with ample space.
This species changes colour when afraid.
Typically, they become pale or brownish.
Several specimen of this species can coexist in the same aquarium, provided they are introduced simultaneously.
This species can be bred in captivity, one can therefore consider asking your local fish store for a captive bred specimen.
Moonfish (Monodactylidae) are unique, with their special shape and that they have a reflective skin. They are seldom kept in private aquaria, but seen occasionally.
They normally live in brackish water, but can get used to water with a salinity of around 35 (specific gravity 1.026). Larger individuals do better in salt water. Adult fish don´t thrive when moved from their environment, this must be taken into account when these fish are acquired
It is important to mimic their natural environment with proper hiding places, plenty of macroalgae and tree roots.
Because they have the the tendency to swim directly into the glass when frightened, this must be avoided. i.e. dim the light gradually and permanently have a nightlight on.
|Distribution||Indo-West Pacific: Red Sea and East Africa (Ref. 7293) to Samoa, north to the Yaeyamas, south to New Caledonia and Australia (Ref. 4959). Known from the freshwater tidal zone of the Mekong delta (Ref. 12693).|

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
